' WALTER GRANOY BY ATTQRN aYs Sept. 12, 1950 w. GRANOV KNITTING MACHINE5 Sheets-Sheet 5 INVEN TOR. WALT ED. QRANOV Filed April 9, 1949 ATT ORNEYS Patented Sept. 12, 1950 This invention relates to improvements inundergo a, transferring knitting machines and is concerned I moreespecially with knitting machines of the V-bed type having inclinedneedle beds.

In machines of the type indicated two up; wardly inclined needle bedsare arranged sub;

stantially perpendicularly to each other and the knitting operation isperformed in the longi" tudinally extending space between the twoneedle"beds. Needles, and needle jacks or pushers are;

slidable in grooves orchannels formed in each bed and the motion of theneedles and needle jacks are controlled through the agency" of a systemof cam blocks mounted on cam plates" forming a part of the carriagereciprocating over" the needle beds.

'A primary object of the invention is to provide a, novel constructionfor selectively controlling"- the motion of predetermined needles in theneedle beds in such a manner as toincrease or diminish, as desired, thenumber of stitches in successiverows or courses'of a knitted articlewithout requiring interruption of the knitting": operation or resettingof the machine once the; initial adjustments have been made. In carrying out this object of the invention I employ" stitch-transferringneedles substantially of the type disclosed in Patent No. 2,326,694issuedto Julius Sirmay and dated August 10, 1943. These needles are ofthe sliding, latch type and are pro vided with a laterally extendingloop-opening,

transfer clip. While the identified patent illus trates a transferneedle having a transfer clip" extending on the right side of the needlebody, I find it necessary'to employ two types of such transfer needles,one having a transfer-clip on the right side of the needle body andthe'other: having a transfer clip. on theleitside of theneedle body, theneedles being arranged-sym--' metrically with respect to the centralaxis of symmetry of the knitted article and the wan verse center line ofthe needle beds and the arrangement of the transfer clips on both sides1 of the transverse center line of the machine being determined by thedirection in which it is desired to diminish the stitches, as willappear more fully hereinafter.

Another object "of the invention i's thepr'ovision of a novelconstruction of'the character I iirows at different portions of thegarment;

indicated including a novel arrangement "of cam" blocks and a dualjack'control of eachtransfer clip needle so that for a single traversingmove ment of the'carriage over the needle bedtit'will operation,subsequent to: their knitting operation, wherein their loops'will betemporarily. transferred ,toian adjacent needle; ofnthe rear -b edrth'ediminution of one or more stitches-,. in. thessucceeding ;row of thearticles beingaccomplished upon the return stroke ot;v the carriage bythe transfer of; the previouslytransferred .stitchiornstitches-irom theneedle of the r arrbed .toaarespective needle ofthe;

Referring now to the drawings in greater detail,

movement of certain of the needles to transfer position in a continuous,automatic operation without any interruption of the knitting operationand without any interference with the normal reciprocatory movement ofthe carriage.

In the drawings the needles '22 and 22a are illustrated as being of thesingle latch type having transfer clips 25 and the movement of eachneedle into operative engagement; with selected camblocKson Caiirplatesi 23 and Z lis controlled by preadjusting one or both jacks orpusher .elements 26 and 21 in a manner to be more fully described. Forpurposes of convenience and clarity; elements 25 will be designated theinner jacks or pushers and elements 2'! will be designated the outerjacks or pushers corresponding to their disposition within the needlebed. are taken on lines l2--l2, l3-l3 and I l-I4;

front and rear beds are upwardly inclined and substantiallyperpendiculafto each other. Il'ach of said needle beds is provided witha. plurality. of grooves or channels which slidably retain knit ingneedles having stitch-transferringmeans or,

so-called transfer clips which are operative in. the

position of extreme forward projection of the:

needle, hereinafter designated the transfer posi# tion.

An important feature of the invention resides in the provision'otineansincluding dual jacks or pusher elementsfor each transfer clip needle anda novel arrangement of cooperating cam blocks mount'ed'on the underfaceof the reciprocating carriage of the machine so that certain of theneedles may be preselected for movement to transfer position and thetransfernormally occurs duringthe reciprocation of: the

ring of one or more stitches maybeaccomplished simultaneously with theknitting operation which carriage. The arrangement'ofthepresen'tinvention establishes an autoniatic'seciuence of operationswhereby all of the needles (including those needles preselected formovement to trans feet position) executea nanngdeeranon, the" knittingoperation; a subsequent nt'eh n'ansfn ring operation, as will "bemereruu ues n ea hereinafter.

' preselected needles executing; mana ements" It has been founddesirable to employs'titchtransferring needles having transfer clips 'ofthe type described in theaforementioned PaI tehtNo. 2,326,694 to JuliusSir'may wherein the transfer clips are illu strated extendinglaterallyltne right side of thenee'dle body. However, since the];

diminution of the num r of stitches in successive rows of a fashionedknittedarticle will generally be carried out symmetrically on bothsidesfo'f the article, as shown in'Fig. l, it'i s'n'ecessary to employtwo types of transfer needles, one having a. transfer clip on the rightside of'the'needle body which has been designated 22 and the other type,

Each cam. plate carries on its underfa'ce a plu-' rality of cam blocksarranged in such a manner as to'control the movement of 'allth needlesto their knitting position" and: to selectively control the" Needles 22and 22a, inner jacks 25 and outer jacks 21 are provided with projectionsor lugs 22b, 26a and 27a. respectively-l andare actuated within theirrespective channels by tha-en gageme t of 1 said lugs against respectivecontrolling camscan ried by cam plates 23 .andi l inrorde tOePQlflform;
